GST/HST and ITC support

AI GST/HST review for Canadian CPAs

Upload a transaction export and get a GST/HST workpaper: estimated tax collected, ITCs, net tax, and a row-level exception list showing exactly which transactions need a second look.

How it works

1. Step 1

   Upload a transaction export

   Attach the sales/purchase export from the client's books — one CSV or XLSX.

2. Step 2

   The workpaper builds itself

   Deterministic logic estimates tax collected, ITCs, and net tax by province and tax code.

3. Step 3

   Review the exceptions

   Download the prepared workbook and work the row-level exception list, not the whole file.

What you get

• Tax summary
• Prepared workbook
• Exception list

Frequently asked questions

Does it handle QST and provincial rates?

Yes. The workpaper recognizes GST, HST, and QST columns and flags rows whose tax doesn't line up with the expected provincial rate.

Is this a filing?

No — it's review support. The workpaper estimates net tax and surfaces exceptions; a CPA reviews and decides what goes on the return.

Is the output generated by an LLM?

No. The workpaper numbers are computed by deterministic spreadsheet logic — the same inputs always produce the same outputs. AI is only used to route your request and explain the results, so every figure is traceable to source rows.

What happens to my uploaded file?

Files are processed to build your workpaper and stay attached to your private conversation. They are not used to train models.
